In which DLL are OpenGL extensions stored?

[halo]

This is going to be a little different.

I need to access some OpenGL extensions commands. Stop! I have the headers files already! The problem is, I don't use C/C++.

BlitzPlus can access opengl32 directly. The way it does this is with function declaration files:

.lib "opengl32.dll"
glAccum ( op%, value#)
glAlphaFunc( func%, ref# )
glAreTexturesResident( n%,textures*,residences*)
glArrayElement( i%)
glBegin( mode% )


However, when I add this line to the declaration file, it says the command is ont found in the DLL:
glActiveTextureARB(a%)

Are these commands in opengl32.dll, or in another one?


Thanks.

In order to use extensions your development environment must be able to load functionpointers at runtime instead of finding them at design time.

You should be able to make a 'stub' ( often a variable) that is a definition of the functions in/out parameters, and on runtime do something like

glActiveTextureARB = wglGetProcAddress('glActiveTextureARB');

Arghhhhhh! Kill me!

So I guess what this will take is a DLL written in C/C++ to access the function pointers.

Try GLEW, most of the work seem to be already done. http://glew.sourceforge.net/

If GLEW is too complex for your case, follow the links to other libs : gluX or EXTGL.

Forgive my ignorance but what is BlitzPlus?
